Everyone always wants light wheels. Anyone can find those easily. I am looking for some extremely light rotors. Stock or near stock performance is preffered. I do not road race my EVO so if they are a little less performing than stock then it is fine. It's pretty much a weekend car.

Anyways, when I had my 350Z I remember seeing some titanium rotors. Very light but I don't think they dissipated heat as well as stock. I don't necessarily want Ti rotors, but what is out there that is significantly lighter? Anything?

BTW, I don't really want to change calipers.

 

There's several threads here about rotors, heat and their weight. I suggest going through those and reading them. It seems you may not grasp how the rotor actually works. {Energy absorbtion then radiate.} I think for weight reducing purposes you may want to search for "2-piece rotors". They come with an aluminum hat that has replacable discs. I've never heard of Ti rotors. If there are some I bet they're hella expensive. Stick with the proven cast iron.

I know there's many people here who disagree, but stay away from the drilled rotors.


You do have another option of ceramic rotors like on the Porsche (GT3 i think) but they cost more than your car.

 

Expensive: Stasis $900/pair http://www.stasisengineering.com/index.shtml (call and ask for Ryan)
Less Expensive: Baer $560/pair http://www.machevo.com

Note: both weigh about 16lbs each versus the stock 26lbs.

 

I can't find any helpful sentences in your response. Thanks for trying though. It means a lot. There is nothing in my post indicating rotor knowledge or lack thereof. Shame on you and your poor assumptions.

 

Thanks for the help! This is a good start.

 

I had not seen the Baer, and the price is very reasonable. I've always been impressed with their products.

TEX, be prepaired for some noise. Not saying they are going to be loud, but they could be.

 

yeah there was a good thread on rotors, and lightest is not necessarily the best, you actually want some weight on them, i can't remember where i read this,

 

It depends on your purpose. You don't want weight for acceleration. I want to accelerate.

 

Extra mass in the brake rotor will allow it to (very simply put) absorb more energy. The Evo rotors have a lot of mass in the hat area, which IMO does a great job of heat sinking a lot of energy right to the wheel bearings. 2 part rotors replace all that cast iron in the center of the rotor with a nice light Al hat.

Some of you actually educated in thermodynamics might want to explain how mass in the hat area does not do a lot for brake performance.
